Tìm x, biết:
x^10-x^8=0
Tìm x biết
a) (x-8)(x^3+8)=0
b) (4x-3)-(x+5)=3(10-x)
tìm x biết
a/ (x-8)(x^3 +8)=0
b/ (4x-3)-(x+5)=3(10-x)
tìm x, biết:
a, (x - 8) (x3 + 8) = 0
b, (4x - 3) - (x + 5) = 3(10-x)
Tìm x biết :
a) ( 2x - 3 ).( x +1 ) > 0
b) ( x + 5 ).(x-7) < 0
c) | 2x - 3 | + 8 = 10
d) ( 2x + 5 ) . | x -8 | . ( x2 + 1 ) = 0
Bài 3:Tìm x biết:
a) ( x - 8 ).( x3 + 8 ) =0
b) ( 4x - 3 ) - ( x + 5) = 3.(10 - x)
Tìm x , biết
a) \(\frac{8^{10}+4^{10}}{8^{11}+4^{11}}\)
b) x(x-2015)-2+2015=0
3. Tìm x, biết: a) 2x + 8 ≤ 0 b) 4x-7 ≥ 2x -5 c) (2x-8)(15-3x)>0 d) (10-2x)(8+2x)≤0
